Duplicate Symbols compiling SDK on Mac

[EN8lvVPyrXVsNved3pcP]

I am attempting to compile the SDK on Mac os X 10.9 and running into the following issue with duplicate symbols. It starts here :

-I/Users/Jon/epiphany-sdk/srcw/sim/epiphany/../../opcodes -I../../intl -g -O2 -o run \
nrun.o libsim.a ../../bfd/libbfd.a ../../opcodes/libopcodes.a ../../intl/libintl.a -liconv ../../libiberty/libiberty.a -lz -lm
duplicate symbol _sim_addr_range_hit_p in:
nrun.o
libsim.a(sim-arange.o)
duplicate symbol _sim_addr_range_hit_p in:
nrun.o
libsim.a(sim-command.o)
duplicate symbol _sim_addr_range_hit_p in:
nrun.o
libsim.a(sim-config.o)

......

Continues for a long wihle and ends here

duplicate symbol _sim_addr_range_hit_p in:
nrun.o
libsim.a(epiphany-fp.o)
duplicate symbol _sim_addr_range_hit_p in:
nrun.o
libsim.a(devices.o)
duplicate symbol _sim_addr_range_hit_p in:
nrun.o
libsim.a(traps.o)
ld: 255 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [run] Error 1
make[1]: *** [all] Error 1
make: *** [all-sim] Error 2

It seems that others have gotten this to work on Mac so I obviously must be doing something incorrectly. I used MacPorts to install the dependencies as indicated in the install documentation. I have the latest xcode and command line tools installed version 5.0.2.

Any suggestions on what to look for ?

Thanks in advance for any assistance.

Hi Jeremey,

Yes it would appear so. As far as I know that is the default compiler when you have Xcode 5 installed. Is that a problem for compiling the SDK ?

Here is the output from the command line for the gcc version number

gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix

Any suggestions on how to fix this ? It made it quite a way through the process before failing.

Hi Jon,

Yes - I agree others have this working in Mac environments. I'll consult with Simon Cook, who is our local Mac expert. I'm not sure how long LLVM has been the default compiler, or how effective LLVM is in cross-compiling GCC. I note that the actual error is a binutils error, and as far as I am aware Mac still uses GNU binutils.

More news later...

Hi Raymond,

Thanks for the update. I will have to give it a try. One question though... did this break your ability to compile xcode projects in any way ?

[rsneekes]

Haven't tested that yet after this yet, but it shouldn't. When you don't need the macports gcc, you can do "sudo port select --set gcc none" to disable it again.

Just tested Xcode with a small OSX project and a bigger iOS project and both compiled/debugged without any problems.
